Question

你好。我在asp.net中的另一个div中创建了一个新的div。现在我想使用新创建的div的innerhtml属性。我找不到办法......

这就是我在.aspx页面中所做的..

      <asp:ScriptManager ID="ScriptManager1" runat="server">
      </asp:ScriptManager>
      <asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <ContentTemplate>
            <div id="forNewEmployee" runat="server"></div>
        </ContentTemplate>
        <Triggers>
            <asp:AsyncPostBackTrigger ControlID="link" EventName="click" />
        </Triggers>
      </asp:UpdatePanel>

     <div class="addMore">
      <asp:Button ID="link"  CssClass="label"  runat="server" Text="Add More - Image" 
          onclick="link_Click" />
     </div>

并在codebehind文件..

protected void link_Click(object sender, EventArgs e)
{
    if (clickCheck != 0)
    {
        // access the newly generated div 'forNewEmployee' + specific id and call its innerHtml Method?
        System.Web.UI.HtmlControls.HtmlControl div = (System.Web.UI.HtmlControls.HtmlControl)ScriptManager1.FindControl("forNewEmployee" + clickCheck);

    }
    else {
        this.forNewEmployee.InnerHtml = newRow();        
    }
}

我有一个函数，我正在构建字符串以在forNewEmployee div中引入新元素。这是如何定义..

protected string newRow() {
    // check for click
    clickCheck++;

    // check for new row
    countForEmployee++;

    // building our new row
    rowString.AppendLine("<label for='empName" + countForEmployee.ToString() + "'>Your Employee Name: <span>(required)</span></label>");
    rowString.AppendLine("<input id='empName" + countForEmployee.ToString() + "' class='registrationformEmployeeText' />");
    rowString.AppendLine("</div>");

    rowString.AppendLine("<div id='forNewEmployee" + countForEmployee.ToString() + "' name='forNewEmployee" + countForEmployee.ToString() + "' runat='server'></div>");

    return rowString.ToString();
}

我不完全确定您可以使用div执行此操作但请确保您可以使用asp:Panel执行此操作：

this.forNewEmployee.Controls.Add(new Literal(newRow());

最简单的方法是使用asp .net面板，创建并添加asp .net控件（即使它们是文字控件）。

所以基本上你的NewRow功能将是：

protected Panel newRow() { 
   // check for click 
   clickCheck++; 

   // check for new row 
   countForEmployee++; 

   // building our new row 
    Panel pnl = new Panel();
    pnl.Controls.Add(new Literal("<label for='empName" + countForEmployee.ToString() + "'>Your Employee    Name: <span>(required)</span></label>"));
    pnl.Controls.Add(new Literal("<input id='empName" + countForEmployee.ToString() + "' class='registrationformEmployeeText' />"));

    Panel forNewEmployee = new Panel();
    forNewEmployee.ID = "forNewEmployee" + countForEmployee.ToString();

    pnl.Controls.Add(forNewEmployee);

    return pnl;

}

这样，您就可以使用您指定的控件ID执行FindControl。
